The Environment Canada Water Office’s Data File for Britannia Station is downloaded for processing every hour from April to October, and every 4 hours from November to March. Please note that occasional data gaps may occur, which are indicated by periods of constant water levels over multiple time intervals.
1 It is worth noting that the Britannia Station water level and flow metering station is located at NSC!
